See "Quorum Disk (Quorum Resource)" and the MSCS online documentation for more information.
NOTE: PowerEdge Cluster SE500W solutions do not support the Majority Node Set (MNS) Quorum resource type.
Shared Storage Systems
Cluster nodes can share access to external storage systems; however, only one of the nodes can own any RAID volume in the external storage system at any time. MSCS controls which node has access to each RAID volume in the shared storage system.
Dell OpenManage™ Array Manager or Dell OpenManage enhanced Storage Manager provides storage management and monitoring for SCSI storage components. See your Array Manager or OMSM documentation for more information.
PowerEdge Cluster SE500W Solution
The PowerEdge Cluster SE500W solution implements
•High availability of system services and resources to network clients
•Redundant storage for application program data
•Failure recovery for
•Flexible maintenance capabilities, allowing you to repair, maintain, or upgrade a cluster node without taking the entire cluster offline
Each cluster node is configured with software, storage, and network resources that enable it to monitor and interact with the other node to provide mutually redundant operation. If a cluster node fails for any reason, virtual servers and resource groups are failed over to the healthy cluster node. When the failed node is repaired and brought back online, the virtual servers and resource groups are failed back to the repaired node (if desired).
The cluster nodes, therefore, operate as a single resource, rather than a collection of individual systems. Because the cluster nodes interact in this way, each virtual server appears as a single system to the network clients.
